Oregon Highways

A Highway is defined as a road that is maintained by the Oregon Department of Transportation and is identified by a name and a "secret" number (sometimes referred to as a Road Number). These numbers normally do not coincide with published and marked Route Numbers seen on road maps. However, starting in 2002, ODOT began assigning route numbers to all "unnumbered" Highways. Many of these "new" route numbers are assigned based on the highway number, except when the number assignment would result in a duplication of an existing route number.

History
1932 Gousha Oregon Map
A clip from a 1932 Oregon Road Map printed by Gousha for Shell showing the original Oregon Highway Numbers instead of the current Route Number System.

Originally, the Oregon Highway names and numbers were used as the primary identification of state routes. The first route markings showed up in Oregon in 1926 with the implementation of the US Route Systems. In 1932, the Oregon Route System was devised to prevent confusion between US Routes and Oregon Highways, but the original Highway names and numbers were kept for internal Oregon Highway Division (DOT) uses.

As new Highways were built, the Highway name and numbering system was retained even though other Route numbers were assigned these same Highways. As new sections of Highways were built, older sections were often given new names and numbers and kept in the Highway system. Other sections were turned over to local jurisdictions or totally being replaced by other Highways. Such an example is the case of the newer Whitney Highway #71 replacing the older Baker-Unity Highway #13 and creating the Dooley Mountain Highway #415.

In some instances, local jurisdictions or the state have requested swaps of highway properties. Many times these jurisdictional swaps occur to return local control to minor highways for state control of major highways. The swap for Belt Line Highway #69 with the Junction City-Eugene Highway #223 in Lane County in the 1980's is an example of such a swap.

 

Highway Classification

Highways are defined as either Primary Highways (Numbered 1-100) or Secondary Highway (Numbered 101-459).

The first two digits of the three digit Secondary Highway number usually identifies the county that the highway originates in, but there are a couple of exceptions. The numbering pattern of Secondary Highways follows a regional pattern across the state starting from Clatsop County in the northwest to Malheur County in the southeast.

 

Note

In the past, some map publishers incorrectly publish these secret Highway numbers on maps. Until recently, Oregon did not post these Highway numbers in any form on their road network. However, starting in 2002, ODOT started assigning new route number to previously "unnumbered" highways. In many instances, these route numbers match the secret highway numbers.
